If you use Firefox web browser, bear in mind there is an issue with Bookmarks. Do a Google search to find more information and get a Bookmarks backup. This issue was supposed to have been fixed in the latest version - but I think it lingers.
Yesterday, my system rebooted (for a reason I'm still checking) and when it came back up all the Firefox bookmarks had been deleted and/or overwritten. As far as I am aware, this is a Firefox issue - not a virus. Having many bookmarks suddenly go missing is a catastrophe you might want to avoid. That's why I suggest you look into backing up Firefox bookmarks.
